Trying to create a type generic which will allow or restrict from specifying only one key (or no keys at all). UPD1: shown keys are just specific for target task. The question is about if it's "legal" to pass real-values in generic like in C++ templates. True or False for T. UPD2: The answer is no, it just doesn't work like that cause the Template parameter alwas has TypeVar type
